Abstract
An injection molding machine has an improved lock and block system wherein the lock recess on the ram is defined between the parallel faces of a pair of spaced apart rings. The lock recess is established at a preselected position by sliding various ones of the rings longitudinally forward or rearward on the compression ram to coincide with a preselected advance position of the compression ram (blocking ram) on which is mounted the movable platen. The rings may be spaced apart by a magnetic spacer which is positioned where it will not be struck by moving parts of the machine. At least one jackhole or toolhole is provided in the side of the ring so that it can be separated from adjacent machine elements during set up operations.
